A car that can drive itself has successfully completed its first public test drive on the streets of Berlin. The VW has been specially adapted by experts at Berlin's Free University. A computer controls the steering, brakes and acceleration while scanners, radar and cameras monitor other traffic. Meanwhile, a precision GPS system means that the car always knows where it is to within a one metre margin of error. However, it is still not considered foolproof and needs a driver behind the wheel, just in case it decides to crash itself. Berlin Free University's Paul Rojas said: "The car is intelligent in that it can recognise its surroundings. It can react to events. "Of course, it doesn't compare to an real life form - it's an intelligent artefact."
